Tlie outer end of the locking plunger 10 may be provided with a side recess 14 which is exposed at one side of a depressed seat 15 formed in the front of the nut 6 adjacent the outer end of the opening 7. This recessl l of the locking plunger 10 can be. engaged by an end of the retaining pin 12 for the purpose of ing pin from position if it should become wedged or stuck.

A slight modification is shown by Fig. 5, locking plunger 10 is formed with a pair of spaced grooved portions 11 and also with an outwardly facing shoulder 16 which is engaged by a spring 17, said spring normally tending to move the plunger.

This spring is shown as surrounding the plunger and lnterposed between the shoulder 16 and a guidering 18 screwed into the outer end of the opening 7 The retainingv pin 12 is contractedexactly as in the previous instance, being designed to engage either one of the grooved portions 11? of the locking plunger for the purpose of holding the locking plunger in either an operative or inoperative position.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is e V 1. The combination with a bolt having a flat side, a washer fittedslidably upon the bolt and having a flat side for cooperation with the flat side of the bolt to hold the washer against rotation, said washer being provided with anannular series of openings, anut threaded uponthe bolt and provided at one side thereof with a longitudinal opening arranged parallel to the axis of the nut,

and also, with a transverse'opening intersecting the longitudinal opening tangentially forcibly prying the lockand opening through the sides of the nut, a locking, plunger sliolable within the longitudinal opening of the nut and adapted to be moved into engagement with a selected one of the openings of the washer to lock the nut against rotation, said locking plunger-being provided at an intermediate point in its length with spaced grooved portions, and a retaining pin insertible through the transverse opening of the nut and adapted to engage either selected one of the grooved portions of the locking plunger to hold the latter in either a retracted or a projected position. r "1 2. Thecombination with a bolt having a flat side, awashe'r fitted slidably'upon the bolt and having a flat side for cooperation with the fiat side of the bolt to hold the washer against rotation, said washer being provided with an annular series of open ings, a nut threaded upon the bolt and provided with a longitudinal o'peningjarranged parallel to the axis of the nut and also with a transverse opening intersecting the said longitudinal opening tangentially and opening through the sidesof the nut, a spring actuated plunger slidable within the longitudinal opening ofthe nut and adapted to be projected into engagement with a selected one of the openings in thewasher member to lock the nut against rotation, said plunger being provided at its outer end with a finger piece adapted to be. grasped when retraeting it, and being also provided with a pair of spaced grooved portions, and a retaining pin insertible in the transverse opening of the nut for engagement with either selected one of the grooved portions of the plungerto hold the plunger in either a projected or a retracted position. V

V 3. The combination of a bolt having a flat side, a washer fitted slidably upon the bolt and having a flat side for cooperation with the flat side of the bolt to hold the washer against rotation thereon, said washer being provided with an annular series of openings, a nut threaded'upon the bolt and provided with a longitudinal opening extending 7 parallel to the axis of'the' nut, and also with a transverse opening intersecting the longitudinal opening tangentially and opening through the sides of the nut, said sides of the .nut being provided with short grooves communicating with the ends of thetransverse openlng and havingdepressed seats at the sides thereof, a locking plunger slidable within the longitudinal opening and adapted to be projected into engagement with one of the openings of the washer to lock the nut against rotation, said. locking plunger having a grooved portion, at an intermediate point in the length thereof, and a retaining pin inserted. through the transverse opening of the nut for engagement with the grooved portion of the plunger to hold the plunger in operative position, the extremities of the retaining pin extendingbeyond the sides of the nut and being returned into the before mentioned short grooves, the depressed seats at the sides of the grooves enabling the said returned ends of the retaining pin to be engaged by a tool when it is desired to remove the retaining pin.

4:. The combination of a bolt having a fiat side, a washer fitted slidably upon the bolt and having a fiat side for cooperation with the flat side of the bolt to hold the washer against rotation, said washer being provided with an annular series of openings, a nut threaded upon the bolt and provided with a longitudinal opening arranged parallel to the axis of the nut, and also with a transverse opening intersecting the longitudinal opening tangentially, a depressed seat being formed in the outer face of the nut adjacent the longitudinal opening thereof, a locking plunger slidable through the longitudinal opening of the nut and adapted to be'projected into engagement with one of the openings of the washer to lock the nut against rotation, the outer end of the plunger being formed with a side recess which is exposed through the depressed seat of the nut and also with a grooved portion'at an intermediate point in the length thereof, and a retaining pin insertible into the, transverse opening of the nut for engagement with the grooved portion of the plunger to look the plunger in operative position, said retaining pin being also adapted to be brought into engagement with the side recess of the plunger for forcibly withdrawing the same when necessary,

5. The combination with a bolt formed with a flat side, a washer fitted slidably upon the bolt and having a fiat side for cooperation with the flat side of the bolt, said Washer being provided with an annular series of openings, a nut threaded upon the bolt and provided at one side thereof with a longitudinal opening arranged parallel to the axis of the nut, and, also with a transverse opening intersecting the longitudinal opening tangentially and opening through the sides of the nut, said sides of the nut being moving the pin, said ends being adapted to V be returned into the before mentioned short grooves at the ends of the transverse op'ening to hold the retaining pin in position, the

grooves providing protection for the ends of the retaining pin to prevent the same from being broken off or caught in adj aoent objects.

In testimony whereof I have slgned my name to this specification in the presence of a two subscribing witnesses.
